Recent Advances in Water Engineering

Recent Advances in Water Engineering

Recent ​advances in ​Civil ​Engineering are ​quite a few; ​however, it is ​equally true ​that much of ​the current ​research in ​Civil ​Engineering is ​exceedingly ​pedantic with ​very questionable ​practical ​utility.

Too ​much attention ​is often ​focussed on ​issues that are ​of peripheral ​importance to ​the profession ​of Civil ​Engineering ​leaving ​pressing ​matters ​unattended. ​This is ​precisely what ​is impeding the ​development of ​the technology ​and the ​business of ​Civil ​Engineering at ​a pace similar ​to that which ​we see, for ​example, in ​Computer ​Science and ​Engineering. 

That said, it ​is indubitably ​true that Civil ​Engineering has ​developed and ​advanced in ​quite a few ​areas. Let us ​zoom in on one ​such area, ​Water ​Engineering. ​Water ​Engineering ​includes Fluid ​Mechanics, ​Hydraulics, ​Hydrology, ​Water Resources ​Engineering, ​Wastewater ​Engineering, ​Groundwater ​Quantity and ​Quality-related ​Issues and ​Water ​Management. A ​huge amount of ​research has ​been done and ​thus a huge ​number of ​publications ​have been made ​in the field of ​Water ​Engineering ​recently.​

Among the ​research ​problems that ​have been ​addressed in ​Water ​Engineering in ​recent times, ​the following ​are worth ​mentioning.​
 

Continuing our ​focus on Water ​Engineering, ​making ​available ​drinking water, ​of adequate ​quantity and of ​acceptable ​quality, to the ​population is a ​major issue ​that must be ​addressed ​by the Civil ​Engineering ​profession.​ It is a fact ​that the ​piezometric ​level of ​groundwater is ​decreasing, ​sometimes at an ​alarming rate, ​under most, if ​not all, major ​cities.​ In large ​cities built on ​coastal ​alluvial soil, ​like Kolkata ​and Bangkok, ​this is causing ​soil consolidation ​and land ​subsidence ​which in turn ​is resulting, ​in some cases, ​to distress in ​superstructures.​ Sometimes, the ​quality of the ​water being ​supplied to the ​residents of a ​city is in ​the spotlight. Saline water ​intrusion ​plagues coastal ​areas and is a ​major problem ​in cities like ​Chennai. In ​certain other ​cases, presence ​of arsenic or ​fluoride or ​both in the ​water source ​necessitate ​extensive ​treatment of ​the water ​before it can ​be supplied to ​the residents of a city.

Let us now ​take a look at ​two unsolved ​problems of ​current ​research. First,​ the issue of ​earthquake ​hydo-​geotechniques ​for strong ​earthquakes has been ​addressed only ​qualitatively ​as a quantitative ​analysis still ​eludes the ​Civil ​Engineering ​profession. ​Second, no ​attempt has ​been made to ​determine ​exactly or even ​approximately ​the total soil ​consolidation ​due to the ​combined effect ​of groundwater ​depletion and ​superstructure ​loading. For ​the first ​problem, I have ​arrived at an ​approximate ​solution. For ​the second ​problem, I have ​proposed that, ​to begin with, ​a linear ​addition of the ​soil consolidation ​due to the two ​phenomena be ​done as a first ​approximation ​to the actual ​soil consolidation.​

The Civil ​Engineering ​profession must ​aim at ​sustainable ​development. ​Sustainable ​development ​implies ​development in ​a manner that ​is well thought-​out, that does ​not harm the ​environment, ​that can be ​sustained ​without the ​need to ​radically alter ​the development ​strategy due to ​insufficient ​thought-input ​during the ​process of ​formulating the ​development ​strategy and ​that is marked ​by wisdom in ​chalking out ​all steps of ​the development ​process. For ​cities, ​having green ​zones in a city,​ harvesting ​rainwater to ​augment water ​supply and ​using solar ​panels to ​generate ​electricity are ​all good ​practices that ​should be ​embedded in any ​city-planning ​plan.
